SAID FULLER TILTING AND CENTERING TABLE.

Application filed September 15, 1924. Serial No. 737,750.

on the drawings representing like parts.

Our present invention relates to brick making machinery, and more particularly to a hacking machine for mechanically handling the brick during the process of manufacture and concerns that part of the manufacture of taking the br cks as they issue from the drier and arranging such bricks in hacked relation preparatory to the bricks being built into a kiln by a mechanical loading device.

The present invention, therefore, relates to an improved tiltable table, the platform of which is composed of a plurality of parallelly arranged troughs, the bottom of such 1 troughs consisting of parallel rows of antifriction members for facilitating travel of bricks throughout the length of the troughs, and such table has associated therewith means for moving the entire table transversely of the direction of the flow of bricks. s

In the accompanying drawings illustrating the preferred embodiment of our invention,

Fig. 1 is an end elevation, and

Fig. 2 is a side elevation.

- Referring to the drawings, we have shown a platform composed of uprights 10 having secured thereto at their bottom ends floor members 11 of angle iron and at their top ends with longitudinally extending inverted channel members 12 and transverse channel members 13, braces 14 and plates 15 being employed in the usual manner to make the entire structure rigid. Secured'to the inverted channel members. 12 by bolts and nuts 16 and 17 respectively are track members 18, V blocks 19 being spaced apart throughout the length of the members 12.

50 A rectangular frame comprised of channel members 20 extending longitudinally of the frame and being secured to channel members 21 at the ends thereof is provided with a transversely extending member 22 to which is attached one end of a member 23, the

other end of this member extending downwardly and is attached to the outer end of aplunger shaft 24 mounted for reciprocation in an air cylinder 25 that is mounted on the transverse channel members 13, suitable control devices for the air cylinder 25 being provided for admitting air to one or.

the other end of the cylinder, as may be desired, to cause a reciprocatory motion of the plunger shaft 24 and, therefore, a reciprocatory motion of the framework comprised of the members 20 and 21. Secured to the longitudinally extending members 20 at each end thereof are bearing members 26, these bearing members being arranged in pairs and rotatably mounted in each pair of bearings 26 is a shaft 27 having secured near each end adjacent the bearings 26 grooved wheels 28 which roll on the tracks 18. Secured toeach end of the members 21 and centrally arranged with respect thereto is a block29 and secured tot-he top of each block 29 in a depression formed for the purpose is a section of shaft 30, these sections of shaft 30 being in alinement with each other. Rotatably mounted on the sections of shaft 30 are bearing blocks 31, each being secured to the under side of an end plate 32 of a platform. This platform is constructed of the end members 32, a longitudinal member 33 secured at one end of the end plates 32 by bolts and nuts 34 and 35 respectively and angle members 36 secured to the ends of the end members 32 and to the under edge thereof, as shown in Fig. 1. Arranged parallel with the end members 32 and spaced apart from the end members and from each other a distance slightly greater than the thickness of a brick are plates 37, these plates being substantially of the same dimension as the end plates 32. The plates 37 are supported on a plurality of rods 38 that extend between the end members 32 and on the rods 38 between the plates 37 and between the plates 37 and the end members 32 are bushings (not shown) which act as spacing members for retaining the plates 37 in spaced relation and which also act as supports for anti-frictions rollers 39, which anti-friction rollers act as the bottom of troughs formed by the plates 37.

Secured to the end members 21 and at each end thereof are uprights 40 provided at their upper ends with cut out portions 41 in each of which is pivotally mounted a lever 42 provided on its lower end with a recess in which is located one end of a coil spring 43, the other end of this spring engaging with the side of the member 40, this spring tending to force the upper end of the lever 42 inwardly toward the tilting platform or deck, and rotatably mounted in the upper end of the member 42 is a roller 44, this arrangement being designed to act as a tripping means for a brick lifting device. The brick lifting device, being arranged horizontal, will engage with one end of the tilting platform or deck, and, by its weight, will swing the tilting platform about the bearing shafts 30 into a horizontal position where it will remain until the bricks are grasped by the lifting device and lifted to be transported to a unit transfer car. The spring 43 holds the lever 42 in its normal position with the roller 44 in position to be engaged by the descending brick lifter.

As shown in Fig. 1, the portion to the left of the tilting platform above described is the receiving end, and mounted adjacent such end on a framework, designed generally by the numeral 45, is a series of troughs or runways 46 defined by parallelly arranged plates 47, the bottom of these troughs 46 being provided with a plurality of parallelly arranged anti-friction rollers 48. Mounted in the extreme end of the troughs defined by the parallelly arranged plates 4'? and extending parallel to the axes of the antifriction rollers 48 is a shaft 49 having secured at one end a pulley 50 over which runs a belt 51 leading from any suitable source of power. Mounted at the receiving end of each of the troughs defined by the plates 37 and by the plates 37 and the end members 32 is an anti-friction roller 58, a shaft 52, extending through the end members 82 and plates 07, being provided to act as a mounting for such anti-friction rollers.

The bricks, moving along the anti-frio' tion rollers 48, are caught up by the rollers secured to the shaft 49, such rollers having a greater surface speed than is given to the anti-friction rollers 48, this construction as sist-ing the bricks in moving onward onto the tilting platform the rollers 53 acting to guide such bricks into position and onto the anti-friction rollers 39 and give them an initial start down the incline toward the end remote from the receiving end.

The angle the tilting platform makes with the horizontal is about 5, this angle having been found sufficient to allow the bricks to roll by gravity down over the anti-friction rollers 39, particularly when such bricks have been assisted by having an initial start off the anti-friction rollers 48, and such angle is small enough to cause no inconvenience when the brick lifting device moves the same to horizontal position. The device, as shown in Fig. 2, is presumed to be in the normal or initial receiving position and, assuming that all of the troughs formed by the plates 37 that are in alinement with the troughs formed by the plates47 to have been filled with brick, the operator will, by properly controlling the flow of air to the air cylinder 25, cause, a movement of the tilting table to the right, as shown in Fig. 2, to bring the remaining troughs formed by the plates 3'? into the alinement with the troughs formed by the plates 47.

hen all of the troughs defined by the plates 37 are filled with brick, the lifting device above referred to, is lowered into position onto the table, being guided into position by the uprights 40. On reaching its lowermost position, the lifting device above referred to (but not shown) has operative portions thereof engaged by the roller 44 which moves the lever 42 outwardly about its pivot point and against thecompression of the spring 43 to effect a tripping of the gripping mechanism on such lifting device, which thereupon automatically causes the lifting device to be raised, carrying the brick that were loaded on the table, upwardly. lVhile we have necessarily shown and described the preferred embodiment of our invention somewhat in detail, it is to be understood that we may vary the size, shape, and arrangement of parts within wide limits without departing from the spirit of the invention.

Having thus described our invention, what we claim as new is:

An improved table for hacking machines comprising a base, a track mounted thereon, a frame, a plurality of shafts mounted for rotation therein, wheels secured to said shafts and associated with the tracks, alined bearings mounted on the top of said platform, and a framework provided with a plurality of parallelly arranged troughs mounted for tilting movement on said bearings.

In testimony whereof, we have signed our names to'this specification.
